    <p>
    Stefan Cornelius (Secunia Research) reported a boundary error within
    the imb_loadhdr() function in in the file
    source/blender/imbuf/intern/radiance_hdr.c when processing RGBE images
    (CVE-2008-1102). Multiple vulnerabilities involving insecure usage of
    temporary files have also been reported (CVE-2008-1103).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted file
    (.hdr or .blend), possibly resulting in the remote execution of
    arbitrary code with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Blender users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/blender-2.43-r2&quot;</code>
  </resolution>
